[Solitary intestinal fibromatosis: an unusual cause of neonatal intestinal obstruction].

: We report a new case of solitary intestinal fibromatosis (SIF) in a neonate with intestinal obstruction in the first day of life. At the laparotomy was found to be due to a solid mass in the jejunum. A segmental jejunal resection with anastomosis was performed. Histologic examination showed a SIF. The postoperative course was excellent in contrast to cases of congenital fibromatosis with multiples lesions, which carries a poor prognosis.
